    I used to work for a copper refinery and we would refine the Cu/Au/Ag& PtGrp metals out of "copper" anodes from places like this. The copper anodes did not draw much attention in shipment they they were too heavy to steal however they were up to 4% Au sometimes or 4% Silver. As an engineer I would represent the company when we sampled these things to determine the value and settle up. The dollar amounts in a 100 ton lot were staggering. Imagine a railcar gondola filled with 800 pound anodes containing 4% Au. One of my task was to determine how much of this stuff we could feed into the copper plant each day without causing electrochemical complications. This was in the before times and the calcs were done by hand.

All of my career work has been on movement and change with respect to geology, so it's more about visuals and seeing spatial changes for me. I'll keep at it, though! Thanks again!

    This mountain may have had the lowest latitude ski resort ever (and the 2nd highest after a Bolivian glacier). That's only based on a few German sources and the ski resort didn't last long. The glacier is almost fully melted now.

    The gold fields in Alabama, and the mineral areas in North Carolina, seems to go against the idea of sedimentary rock. The titanium mines around Raleigh, NC goes against the idea of erosion, unless the earth was eroded out around the metals, leaving a hot spot. Has anyone added the friction of the plate movement that could cause a hot spot during a major movement event?

    Really interesting to learn the geology of it! I learned about the Grasberg mine many years ago for those "not so positive reasons"...seems a common theme with all these New Guinea/Indonesia mines. Government turns a blind eye to uncontrolled release of tailings and horrible treatment of workers, and the vast majority of the wealth goes to foreign companies (Freeport esp egregious...) and don't even help the native country...with widespread accusations of bribery and corruption behind it all. It's all terribly exploitative of people and nature; very sad. But alas, geology was there before any of that so cannot be blamed!

    My understanding of the geology here is this likely would have been slab failure magmatism is a fascinating phenomenon I should note that it is the break in the subducted slab with the disconnection of the oceanic Australian slab from the continental shelf with the oceanic section delaminating as the buoyant continental crust rebounds
    Nick Zentner's A to Z Baja BC series had a really good animation of this failure and ultimately delamination occurring.
    A similar example where this process is ongoing is Taiwan which has recently been accreted onto the Eurasian plate. In essence you had an ocean volcanic archipelago with the Subduction of the Australian plate which is still ongoing within the Sunda trench. This can in principal lead to some crazy batholith generation so I wouldn't be surprised if there is some extensive batholiths that have been emplaced at depth some tens of kilometers down beneath this mountain range.
    If Robert Hildebrand is right this may be the mechanism which much of the Sierra Nevada batholith and The Baja Costal Range Pluton complexes formed though this is still controversial. Note that in California the actual events took place 100 to 80 Ma and were only brought to the surface during the last 30 Ma by extensive erosion of many kilometers of rock so its geologists arguing about the specifics of how this went down, but the point is its possible perhaps even probable that their is a Sierra Nevada like batholith complex down there intruded into the delamination zone and welding the former arc onto the Australian continent.
    And yeah there is apparently a forming subduction zone to the north much as there is in Taiwan via a process known as arc polarity reversal of which these two areas represent the template example by which we interpret the orientation of such volcanic arc rocks. The slab failure melts are apparently chemically distinct from other volcanic/igneous rocks with a different more continental chemical affinity favoring more siliceous melts on average than typical oceanic subduction i.e. they lack the same extent of gabbroic intrusive melts that weigh down oceanic volcanic arcs.

    I worked for a company which made a fair bot of its revenue off supplying consumable to the PT Freeport mine on this mountain. Delivering to the shipping company at the port was always interesting. The pipes the slurry is pumped in aren't small, they're around 45-50cm diameter. Along with this there is continuous replacement of conveyor belts and everything else that wears out with use.
    And yes, there's often trouble in West Papua. It should be an independent and wealthy country based on its mineral wealth, but instead the Indonesian government has continued to brutally oppress the local population.

    • @TheGeoModels
      @TheGeoModels  Месяц назад

      Having mineral wealth is often a very bad thing for many places.
      How long does it take to travel by road from the port to the mine? Does the slurry pipe have to stay in constant operation? I can't imagine that shutting it down and refilling/repressurizing it (or whatever) is an easy task...

      I might work on that. Interestingly, you can't see too much effect from the currrent movement in available lidar because it's older. Landsliding does produce interesting surface damage that isn't always intuitive. I'll see if I can work one in one of these days.

      While gold can be made by r process it should be noted that gold can also be made via the s process which occurs in the red giant phase of lower mass stars so I'm not sure what the ratio of gold is between the two. There are many elements which can only be made by r process elements but gold is not one of them.
